High borosilicate heat resistant round sight glass

High borosilicate heat resistant round sight glass


Reflex glasses is made from tempered borosilicate glass, it can be used with all media at service conditions up to 4MPa and temperature up to 430 °C.

The side facing the medium chamber is provided with molded grooves set at 90°angles. The moulding process increases the resistance of the glass grooves to wear; the skin which the glass attains during moulding gives it maximum smoothness and hardness.This makes it extremely resistant to the attack of boiler water.
It is used on level gauge of boiler for water position. It is also named: Reflex Gauge Glass, Sight glass, Reflex Glasses, Reflex sight glass, Spares For level Gauge.

How To Install And Maintain A Glass Plate Type Level Gauge?

Image
Glass Plate Type level Gauge is a common type level gauge, and the Glass plate include reflex gauge glass (Reflexion gauge glass) and  transparent gauge glass (plain gauge glass or flat gauge glass). It is very important to obey the right method of level gauge installation and maintain to protect the gauge glass part. a). Inspection method of glass plate Type level gauge 1. Remove the bolts and nuts on the glass plate level gauge, and remove the gland, gauge glass gasket, gauge glass and  mica shield  in order (only the level gauge for measuring alkaline medium  has mica shield, in order to protect transparent gauge glass, and other reflex gauge glass type level gauge don’t have mica shield). 2. Clean the dust and oil stains on the level gauge; 3. Remove the rust on the level gauge; 4. Remove the residue of the sealing gasket in the sealing window of the level gauge, taking care not to damage the sealing surface; 5. Trim the sealing surface to make the surface roughn...

Why Borosilicate Glass Is Suitable For Sight Glasses And Gauge Glass

Image
Borosilicate glass mainly refers to toughened (tempered) borosilicate glass. It is a type of glass whose main components are SiO2 and B2O2. It has high working temperature, considerable thermal shock resistance and excellent resistance to chemical attacks. Borosilicate glass has a very low coefficient of thermal expansion, which can withstand high thermal shock, and the glass surface changes very little with temperature. It is the first choice for precision instruments. Borosilicate sight glass contains few ferrous ions and has no obvious absorption in the visible spectral region, so it appears clear, transparent and colorless. It can be used as an observation window for effective and intuitive observation, so it is widely used. Borosilicate sight glass can be processed into flat (such as round, square, special-shaped) glass, and it can also be processed into tubular glass. The flat glass can be polished, drilled, chamfered, and heat treated. The products are widely used in photovolta...
